ADJUSTER r011 META BAnDs.

Application filed June 15, 1927. Serial No. 198,9 82.

This invention relates to metal bands worn with wrist watches, and hasfor its primary ob ect the provision o t an ad usting means whereby ametal band of a given width may be used with watch cases of varyingwidths. Another ob ect of this lnvention 1s that the ad ustmg means alsoacts as a filler between the edges oi the metal band and the protrudinglugs ot the watch case, thereby giving a more pleasing appearance in thejointurebetween the metal band and the watch case. i

v Still further objects'ot this invention are to provide an adjuster formetal bands,

which will be simple, efficient, durable and economical to manufacture.

Other objectsand advantages will be in part indicated in the descriptionand in part rendered apparent therefrom in connection with the drawing.

This invention consists in the provision of a pair of tubularacljustinginembers each having a plurality of slotted recesses in oneend thereof of differentdepths" whereby metalbands of varying widths maybe neatly' and snugly inserted and pivotally attached between the pinbar attaching lugs of a wrist watch. 7

To enable others skilled in the art to fully apprehend the underlyingfeatures hereof that they may embody the same in the various wayscontemplated by this invention, drawings depicting a preferred typicalconstruction have been annexed as a part of this disclosure, in which:

Fig. 3 is a plan view of a watch case having pin bar attaching lugsthereon and showing the inner ends of the metal bands provided with theadjusting sleeves which are positioned between said lugs;

Fig. 6 is an isometric view of one of the pin bars;

Fig. 7 is an enlarged view showing two a purposes I have chosen of thepin holding lugs, two of the adusting sleeves, one of the pin bars andthe looped end o1 one of the metal bands, the

parts shown in horizontal section taken on line 77 of Fig. 8; and

Fig. 8 is a side QlGVELtlOEIOT tllQ parts shown in ig. 7. I

In the embodiment of my invention as illustrated and which shows apreferred construction, I provide a watch case 1 of any suitable size orshape but for illustration j a rectangular shape. Usual pin barattaching lugs 2 are inounted upon the ends 3 and 4, respective- .5 withtransverse holes 5 which detachably receive pins 6 of the usual pin bar7.

The parts thus far described are of th usual andwell-knownconstruct-ion. It has been the practice in the pastto supplyleather straps provided with looped ends forreceiving the pin bars 7 andin this way attaching said leather straps to the pin bar attaching lugs2. ltecently, however,

there has been a demand created for metal j flange 10, as clearly shownin Figs. 2 and 7, Fig. 1 1s a view 111 perspective showing a wrist watchcase having my invention 111- to form a neat and close fit with theattaching lugs and pin bar and on their inner ends with a. plurality ofslotted recesses 11 of difl'erent depths to permit a metal band of agiven width to be attached to watch cases of varying widths. The innerends of metal bands 8 are bent upon themselves, forming loops 12 (seeFigs. 4 and 5) which loops are for the purpose of receiving pin bars 7.It will also be noticed that looped ends 12 of metal bands 8 areslightly cut away at 13, thereby reducing the width of said looped endsrelative to said bands, which cut away.

of said watch casel"an'd are provided I and pin bar that one of theslotted recesses 11 fits over the edge 15 of said hand. Then placeanother adjusting sleeve 9 over the opposite endof said loop 12 so thatone of the slotted recesses 11 fits over edge 16 of said band, whereuponthe band may be securely at.- tached to the pin bar attaching lugs '2 bydepressing pins 6 until the flanges adjusting sleeves 9 fit betwe n Saidlugs, whereupon said pins 6 are forced outwardly into holes 5 of saidlugs 2 by coil spring 14 within said pin bar 7, as is clearly shown in.Fig. 7. As the width between the lugs 2 of watch case 1 varies, a band8 of a given width may be snugly attached therebetween by the adjustmentof sleeves 9, as for example, should the metal bands 8 be of a narrowerwidth than the distance between the lugs 2 the adjusting sleeves 9 maybe so placedupon loop 12 of said band 8 that the smallest slotted recess11 may be inserted over the edges 15 and 16 of said band, thereby givinga snug fit between said band 8 attaching lugs 2.

It will be understood that certain changes and modificationsof theinvention can be made Without departing from the scope or spirit thereofas defined in the claims.

What I claim as newand desire to secure by Letters Patent is:

1. In combination with a watch case hav-- ing lugs and a pin bar adaptedto engage said lugs, a metal band having a looped end and adapted toreceive said pin bar mounted in said lugs and a pair of sleeves eachhaving one end slotted to engage the respective 10' of said said lugs, ametal band havinga loopedend shorter than the width of said band adaptedto receive said pin bar mounted in said lugs,

and a pair of sleeves each having one end slotted to engage therespective edges of said metal band to cause a snug fit between the bandand lugs, for the purposes specified.

5. In the combination as specified in claim 1, wherein one end of eachsleeve is inturned for the purposes set forth.

I 6. In combination with a watch case having lugs and a pin bar adaptedto engage said lugs, a metal band having a looped end adapted to receivesaid pin bar mounted in said lugs, and a pair of slotted sleeves mountedon said pin bar: and engaging said metal band one of which sleeves isprovided with a plurality of slots of varying depths to engage the edgeoisaid metal band whereby a band of a given width may be attached towatches having lugs spaced apart toditferent widths.
